Water transparency (a) and turbidity (b) in relation to abundance (mean number of birds per hourly count; black triangles) and capture success (% = successful captures/total attempts; white circles) of Pied Kingfishers in Densu and Weija (n = 24), south-east coastal Ghana. The linear (y = ax + b) regression lines shown are for the significant negative relationship between transparency and capture success (a), and the significant positive relationship between turbidity and capture success (b)
